Yes lgs do take a lot of practice but I am very glad I learned how to incubate with them! It doesn't take long to learn as long as you learn from your mistakes. You can find a wealth of information here on byc for any problems you are having. In order to learn you should do eggtopsies on all eggs that don't hatch. Doing that can tell you if the temp was off, humidity was too high or low, or if it might be a breeder flock problem. Good luck!
